I will suggest the guide of Survivalist for newer players:
So in the end you still dont really know why you are doing certain things. You are just copying some one else build order without really knowing why it works (or why it also somethings failed). Having said this, i wont suggest to just look for build orders and copy those. Might even be below 800, since i feel like players around 800 elo even try to use build orders nowadays. I dont really know your level, but i guess it is below 1000. So these build orders are highly optimized. Things like this are optimized into build orders. So just dont take stone / gold that early if you dont need it already. Also you need the wood for buildings to advance to the next age and build farms for after sheeps / boars runs out.
In Dark age you mainly wants food to create villagers. So gather the right resources to be able to buy what you need. Things like: Dont have an idle TC, but create villagers all the time. It is all about doing things as efficient as possible. On open maps you can even expect an army in feudal age or even in dark age. This looks like a good Fast Castle build into some pressure.
